Notes on using pogo pin
The pogo pin is a very precise hardware electronic connection device, because its use is special, in order not to affect the use of the product, the following points should be paid attention to when using:
The first point: An important component of the pogo pin connector is the spring.
The spring has a certain range of compression and extension. Therefore, when choosing a pogo pin product, the working stroke and compression of its application environment should be considered, in order to ensure For the service life and stability of the pogo pin, it is best to choose the compression of the pogo pin, which is usually 2/3 of the total stroke; too little press-in and insufficient positive force will cause unstable impedance; too much press-in will cause the tube Mouth bruises, leading to pin stuck. During the assembly process, attention should also be paid to prevent the nozzle from being hit and pin stuck.
The second point: The contact direction. The contact direction of the pogo pin when used has a direct effect on the contact area and contact force of the pogo pin contact. The contact area and contact forces have a direct effect on the contact resistance, so Must pay attention to the contact directly in the design and selection.
The third point: the battery contact piece or FPC gold finger paired with the pogo pin must not be dirty, oxidized, etc
1. There must be no residual sealing liquid; the contact surface of the pogo pin pair must not be dirty, etc.
2. There must be no other dirt residues. Prevent the pogo pin from touching the plastic partition when assembling the pogo pin.
Fourth point: The pogo pinhead and nozzle should be prevented from touching the plastic partition during assembly and use. When pogo pin assembly and application, it is necessary to prevent it from touching the plastic partition. The pogo pin seems to be a simple part, but without good quality control and complete manufacturing process level, it is extremely prone to power failure and pin stuck. Or durability is the problem of a too-short life. Its craftsmanship is relatively delicate and complicated, and every link of lathe processing, electroplating, and assembly may have serious hidden dangers.
